Patented Sept. 23, 1952 UNITED STATES PATENT OFFICE 2,611,258 r DYEING APPARATUS George V. Greaves, Elkins Park, Pa. Application December 24, 1947, Serial No. 793,692

Thisinvention relates to dyeing apparatus.

In dyeing apparatus of the Klauder-Weldon type heretofore available, and particularly by reason of the nature of the dye baths employed, considerable diiiiculty has been encountered with the supporting sticks and their mountings.

It is the principal object of the present invention to provide dyeing apparatus having improved supporting sticks for carrying the skeins and the mountings therefor.

It is a further object of the present invention to provide improved dyeing apparatus in which the yarn supporting rods or sticks have provisions for locking in position.

It is a further object of the present invention to provide dyeing apparatus in which the insertion and removal of the skein supporting sticks or rods will be greatly facilitated.

It is a further object of the present invention to provide improved supporting rods or sticks for carrying the yarn for dyeing. which will have a longer life than the sticks now available and which will not damage the yarn during dyeing.

Other objects and advantageous features of the invention will be apparent from the specification and claims. I

The nature and characteristic features of the invention will be more readily understood from the following description, taken in connection with the accompanying drawings forming part hereof, in which:

Figure 1 is a side elevational view of dyeing apparatus in accordance with the present invention, parts being broken away to show the details of construction;

Fig. 2 is a vertical sectional view taken approximately on the line 2--2 of Fig. 1;

Fig. 3 is a transverse view, enlarged. partly in vertical section and partly in elevation, illustrating one of the supporting rods or sticks employed in connection with the present invention and the mounting thereof; and

Fig. 4 is a transverse view partly in elevation and partly in section illustrating another of the supporting rods or sticks employed in connection with the present invention.

Like numerals refer to like parts throughout the several views.

It should, of courseybe understood that the description and drawings herein are illustrative merely, and that various modifications and changes may be made in the structure disclosed without departing from the spirit of the invention.

2 Claims. (Cl. 68-199) Referring now more particularly to Figs. 1 and 2 of the drawings, a vat or tank Hi is provided having bearings H for carryinga shaft I2 upon which a pair of spaced spiders l3 are mounted. Each of the spiders l3 includes an outer ring or rim M, an inner ring or rim l5 and a hub IS, with radially disposed spokes ll. Extending between and carried by the outer rings or rims M, a plurality of outer sticks or supporting rods i9 are provided, and extending between and carried by the inner rings or rims IS, a plurality of inner sticks or supporting rods 20 are provided, each stick l9 having a'corresponding stick 25! disposed in the same .radial plane through the shaft l2.

One of the outer rings 14 is provided, at spaced locations around the inner surface thereof which faces the inner surface of the other ring l4,'with sockets or cups 2|, the sockets 2| being rotatable in any desired manner such as by means of the star ,wheels 23. The sockets 2| are preferably of square conformation in'the interior for the reception of square ends 24 of the outer sticks or supporting rods I9.

The other of the outer rings I4 is preferably provided with corresponding sockets or cups 22, of round interior shape, for the reception of the round ends 25 of the rods or sticks [9.

One of the inner rings I5 is provided, at spaced locations around the inner surface thereof, with sockets or cups 26 in pairs, each of the sockets 26 of each pair being in radial alinement with one of the sockets 2| on the corresponding outer ring or rim H1.

The other of the inner rings [5 is also provided with corresponding sockets or cups 21 in pairs, in radial alinement with one of the sockets 22 of the outer ring H].

The sockets 26 preferably have interior openings 28 of square conformation for the engagement of square ends 29 of the inner sticks or supporting rods 20 and the sockets 21 on the inner ring opposite thereto preferably have inter'ior openings 30 of round conformation for the engagement of round ends 3| of the inner sticks or supporting rods 20.

The provision of the sockets 26 and 21 in pairs on the inner rings [5 permits of mounting skeins of different lengths as desired.

A preferred construction of the inner supporting rod or stick 20 is shown in Fig. 3.

Each rod or stick 20, and the constituent parts thereof, is preferably of a suitable material re sistant to the action of the dye bath and may be of stainless steel or the like. The stick or rod 20 preferably comprises an elongated cylindrical hollow tubular central portion 33 with a square end 29, as heretofore indicated. The tubular portion 33 at the other end is preferably slotted, as at 34, and a portion 35 of the wall is struck diametrically inwardly with respect to the tubular portion 33 to provide an abutment.

The tubular portion 33 is smaller in length than the distance between the inner rings i and has telescoped in the end 3! thereof, opposite the square end 29, a tubular extension 35, the inner end 3'! of which also provides an abutment. A compression spring 38 is provided in the interior of the end 3| between the abutment 35 and the end 37 of the telescoping section 35, and a rod 39 extending longitudinally through the spring 38 and having pins to at its outer ends provides a limit for the movement of the telescoping sec tion 36 and prevents separation thereof from the tubular portion 33. g

A preferred form of outer stick or supporting rod i9 is illustrated in Fig. 4. Each rod or stick I9, and the constituent parts thereof, is prefer ably made of a suitable material resistant to the action of the dye bath and may be of stainless steel or the like. The rod or stick is preferably includes a central section {H with a square end 24, as heretofore indicated. The exterior surface of the central section 41 is preferably knurled or otherwise shaped to provide a frictional surface 4 la for engagement with the skein for effecting rotation of the skein.

At the otherend of the central sectibnjii, opposite the end 24, a telescoping section 42 is provided, the outer or free end of which is preferably cylindrical and of reduced diameter and the inner end 43 of Whichis provided with an abutment 44. The central sectionfil, at the other end, is preferably slotted as at 45, with a portion 46 transversely or diametrically disposed to provide an abutment. A compression spring 4? is provided in the interior between the abutment M and the abutment 48. A rod 68 is provided, extending longitudinally in the interior, and is provided with pins 49 at the outer ends thereof for limiting the outward movement of the telescoping section 42 and preventing the separation thereof from the central section 85!. I

When it is desired to mount the skeins for dyeing the desired number of skeins are placed side by side on one of the outer rods or sticks I?! which is then positioned with the end 225 in engagement with the socket 22 and the rod or stick is pushed towardsthe end to sheet compression of thesp'ring ii. The square end 2:1 is then seated within its socket 2i and is held therein by expansion of the spring 4?. The inner stick is then inserted in the skeins carried on the outer rod or stick I9, the telescoping portion 38 inserted in theproper socket 221, and the stick 20 pushed towards the end SE to compress the spring 38. The end 29 is then seated in the socket 26 and is held therein by expansion of the spring 38.

The inner stick or supporting rod EUmay be positioned radially inwardly in the desired sockets and 2'! in accordance with the length of the skeins in engagement therewith. Successive pairs of outer sticks 19 and inner sticks 26 are loaded with skeins in the samer'nanner. The spiders 13, with the rods 1'9 and 29 secured thereon, are then rotated by the shaft 12 to bring the skeins of yarn successively into the dye bath in the manner customary with the Islander-Weldon machines.

During the rotation of the spiders E3, the star wheels 23 will be effective in the usual manner for rotating the outer sticks :9, step by step, whereby the skeins in engagement therewith are also shifted in their relationship to the inner sticks 28 and the outer sticks 59.

When it is desired to remove the sticks i2 and 23, this may be readily efiected by pushing the same towards the round ends 25 or 31 so that the square ends 24 or 29 may be disengaged from their sockets, whereupon the round ends 23 or 3| may also be disengaged.

I claim:
